## Repository Structure and Key Files

The Clone-Wars repository structures its data across several key locations:

- **[`README.md`](https://github.com/GorvGoyl/Clone-Wars/blob/main/README.md)** – The central catalog containing the URL-shortener comparison table at lines 73-77.
- **`Atividade_Clone_Wars/`** – Contains the raw data source used to generate the README tables.
- **[`_config.yml`](https://github.com/GorvGoyl/Clone-Wars/blob/main/_config.yml)** – Site configuration for the GitHub Pages rendering of the tables.

When evaluating these **open-source URL shortener alternatives**, prioritize projects that offer **complete API support** (Shlink and Kutt) or **ready-to-deploy Docker setups** (all five projects provide containerization options).

## Programmatic Integration Examples

### Shlink API (Node.js)

The following snippet demonstrates how to create short URLs using Shlink's REST API:

```javascript
const fetch = require('node-fetch');

async function shorten(url) {
  const res = await fetch('https://shlink.example.com/rest/v2/short-urls', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json', 'X-Api-Key': '<YOUR_API_KEY>' },
    body: JSON.stringify({ longUrl: url })
  });
  const data = await res.json();
  console.log('Short URL:', data.shortUrl);
}

shorten('https://example.com');

```

### Polr API (cURL)

For quick integration with Polr, use the API v2 endpoint:

```bash
curl -X POST https://polr.example.com/api/v2/shorten \
  -d "url=https://example.com" \
  -d "api_key=<YOUR_API_KEY>"

```

Both examples assume you have a running instance of the service. Refer to each project's Docker documentation in their respective repositories for deployment instructions.
